Hey, I been there before in the cup before and if it makes you feel any better, my worst defeat was 6-0.

You will have chances to win the cup in the future as your team Levels up, It took me nearly 1 year since starting for me to win the cup for the first time and that was helped by power training a lot of players plus some good team management from myself, I was Level 13, the highest ranked team was Level 16, the power training covered the gap between team quality sufficently. Thankfully that Level 16 club didnt win promotion last season and he's a seasoned player, so I am now 2 levels from the top ranked team so I will have a chance to defend my cup title this season.

Just don't think about winning the cup until you are one of the best ranked teams in the competition.
